Embodiment 1

[0029] A kind of grafting method of polychromatic locust tree, it is characterized in that: comprise the following steps:

[0030] (1) Storage of grafted branches: At the end of December, select various annual branches of pagoda tree, soak them in 400 times carbendazim solution for sterilization and disinfection, and wax them, and seal the wounds of branches with wax to reduce water volatilization ; Store the treated branches in bundles in cold storage, and bury them with sandy soil with a humidity of 40%, and keep the ambient temperature constant at about 5°C;

[0031] (2) Preparation of growth promoter: the growth promoter formula is 95% distilled water, 1% KH 2 PO 4 , 0.4% NAA, 0.6% ZnNO 3 , 0.6% Na 2 SeO 4 , 0.6% MnSO 4 , 1% NaCl, 0.8% CaCl 2 ;

[0032] (3) Treatment of different color pagoda tree bark bud scion

[0033] In the first ten days of March, cut off the scion that is 2cm long and 5mm wide with latent buds on the various pagoda tree branches stored in ste...

Embodiment 2

[0041] A kind of grafting method of polychromatic locust tree, it is characterized in that: comprise the following steps:

[0042] (1) Storage of grafted branches: select annual branches of various pagoda tree branches at the end of December, soak them in 600 times of carbendazim solution for sterilization and disinfection, and process them by waxing to reduce water volatilization; the processed branches Store them in bundles in cold storage, and bury them in sand with a humidity of 50%, and keep the ambient temperature constant at around 5°C;

[0043] (2) Preparation of growth promoter: the growth promoter formula is 95% distilled water, 1% KH 2 PO 4 , 0.4% NAA, 0.6% ZnNO 3 , 0.6% Na 2 SeO 4 , 0.6% MnSO 4 , 1% NaCl, 0.8% CaCl 2 ;

[0044] (3) Treatment of different color pagoda tree bark bud scion

[0045] In the first ten days of March, cut off the scion of 2cm long and 5mm with latent buds on the various pagoda tree branches stored in step (1), and put the scion int...

Embodiment 3

[0053]A kind of grafting method of polychromatic locust tree, it is characterized in that: comprise the following steps:

[0054] (1) Storage of grafted branches: select annual branches of various pagoda tree branches at the end of December, soak them in 800 times of carbendazim solution for sterilization and disinfection, and process them by waxing to reduce water volatilization; the processed branches Store in cold storage in bundles and bury them in sand with a humidity of 60%, and keep the ambient temperature constant at around 5°C;

[0055] (2) Preparation of growth promoter: the growth promoter formula is 95% distilled water, 1% KH 2 PO 4 , 0.4% NAA, 0.6% ZnNO 3 , 0.6% Na 2 SeO 4 , 0.6% MnSO 4 , 1% NaCl, 0.8% CaCl 2 ;

Abstract

The invention relates to the field of horticulture and in particular relates to a method for grafting multi-color sophora japonica trees. The method disclosed by the invention comprises the followingsteps: aiming at the defect existing in the traditional grafting technology that the survival rate is low, taking ordinary sophora japonica growing for 1-2 years as stock, taking various annual sophora japonica dormant buds as scions, treating the scions with a mixed solution having the formula of 95% of distilled water, 1% of KH2PO4, 0.4% of naphthylacetic acid, 0.6% of ZnNO3, 0.6% of Na2SeO4, 0.6% of MnSO4, 1% of NaCl and 0.8% of CaCl2 as a growth promoter, and adopting a rectangular dormant bud compression technology. The grafting survival rate can be effectively improved, the grafting costis reduced, the growth cycle is shortened, and the rapid large-scale breeding effect is achieved.

Description

technical field [0001] The invention relates to the field of horticulture, in particular to a method for grafting polychromatic locust trees. Background technique [0002] Sophora japonica Linn. is a deciduous tree of the genus Sophora in the Papilionaceae (Leguminaceae). There are many kinds of locust trees, such as: the flowers of straight-stalked locust are yellow-white; the flowers of columnar locust are white; the flowers of "safflower" locust are purple-red; the flowers of pink-flowered locust are pink. Sophora japonica not only has excellent medicinal value, but also has unique ornamental value. Although pagoda trees have many qualities and their flower colors are different, each kind of pagoda tree has only one color of flowers, and its ornamental value is greatly reduced. Therefore, the use of grafting technology not only solves the above problems, but also shortens the growth cycle and achieves the effect of rapid reproduction. At present, the grafting technique...
